Not a picture of M81 - The Volcano Nebula : )

This is an experimental image, but I thought I would post it anyway. People with dark skies will probably roll their eyes...

It always happens in January and February, that I am stuck finishing up some winter Milky Way objects with short refractors when the galaxy season sky appears. How do you make a 135mm focal length useful in early galaxy season? I usually just experiment with a target and end up with a 'throw - away' image.

I decided to try something crazy, and image the Integrated Flux Nebula around the M81 M82 area.... from Bortle 8.... with snow on the ground. (My northern skies may actually be Bortle 7.

)
It is certainly not very strong in the image, but the shadow of my real target 'The Volcano Nebula' is definitely there! The best view is the inverted image.

Clear Skies

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
